Title: Timing of a q-switch to suppress pre-lasing of the laser
Inventor: LEGGE DAVID
IPC: H01S3/0941
Filed: 2006-10-18
Granted: 2016-04-12
Abstract: A method for preventing spatial or spectral beam seeding in a Q- switched laser is described. The Q-switch trigger of the laser is delayed by several laser resonator lifetimes after the end of the pump pulse. In this way, beam seeding is completely eliminated whilst pre-lase is maintained. The method described may be used for any laser system where the fall time of the pump radiation is sufficiently fast with respect to the upper state lifetime of the laser medium.

Title: Impact indicator for shooting training
Inventor: LIAO YIN-HSI
IPC: F41J5/08
Filed: 2008-04-15
Granted: 2010-10-26
Abstract: An impact indicator for shooting training, in which an impact indicator includes a pipe body, a light beam module and a compression structure. A wall surface of the pipe body is penetrated with holes, and the light beam module is configured with a switch and located at one end of the pipe body. The compression structure is fitted with a piston at one end remote from the light beam module, and a rod is located at the other end. Accordingly, when air currents are outwardly expelled from the interior of a gun barrel and push the compression structure, then the rod of the compression structure activates the switch of the light beam module, causing the light beam module to emit a light beam. The present invention is thus provided with practical advancement to enable instantaneous indication of the shooting point of impact.

Abstract: There is provided an exhaust system for a small watercraft, which can effectively reduce exhaust noise and, at the same time, allows high output of an engine to be easily obtained at the time of high speed traveling. An exhaust outlet of an exhaust pipe extending from an engine provided in a watercraft body is disposed at a position that allows it to sink in the water at the time when a travel speed of the watercraft body is a predetermined speed or less, and that allows it to get out of the water at the time when the travel speed of the watercraft body exceeds the predetermined speed. An open surface of the exhaust outlet, as viewed from rearward of the watercraft body, is provided so as to be offset toward a side wall surface of a pump chamber from a center of a jet pump in the pump chamber and is made oblique toward the side wall surface toward which the open surface of the exhaust outlet is offset.

IPC: C01B13/02
Filed: 2007-08-21
Granted: 2012-04-24
Abstract: Component gas is separated from a gas mixture. Component gas flow rate, or demand, is determined. One or more gas separator operating parameters is changed based on the component gas flow rate. For example, gas flow rate can be approximated by measuring a rate of pressure decay of a product tank during a time period in which the tank is not being replenished by the separating system. When it is determined that the flow rate is relatively low, operating parameters of the separating system are changed to improve system performance with the lower demand. For example, a target product tank pressure at which sieve beds are switched can be lowered when demand is lower.

Abstract: An ion transfer arrangement for transporting ions between higher and lower pressure regions of a mass spectrometer includes an electrode assembly (120) with a first plurality of ring electrodes (205) arranged in alternating relation with a second plurality of ring electrodes (210). The first plurality of ring electrodes (205) are narrower than the second plurality of ring electrodes (210) in a longitudinal direction, but the first plurality of ring electrodes have a relatively high magnitude voltage of a first polarity applied to them whereas the second plurality of ring electrodes (210) have a relatively lower magnitude voltage applied to them, of opposing polarity to that applied to the first set of ring electrodes (205). In this manner, ions passing through the ion transfer arrangement experience spatially alternating asymmetric electric fields that tend to focus ions away from the inner surface of the channel wall and towards the channel plane or axis of symmetry.
